When using physical cooling for 6 year olds, you can apply warm water externally to the forehead, groin, armpits, palms, feet and other parts of the body. The temperature of the water should be appropriate, not too hot and not too cold, and don’t add anything to the water, especially alcohol and other substances. Physical cooling is a good treatment for low fever, but if the child has a high fever, it is recommended to combine it with anti-fever medication for comprehensive treatment. There are certain reasons for fever, and the most common ones are respiratory diseases and digestive diseases, which can be diagnosed based on the accompanying symptoms, medical history, signs and auxiliary examinations. When it is not convenient to use towels or water for physical cooling, you can take external fever-reducing patches for physical cooling.
